Hi, my name is***** I would like to try to provide helpful advice for the problem you have, which must be worrisome, no doubt.
The advice that I have, is not elaborate. I simply think that you ought to try connecting the phone, via a USB cable, to your computer. If it turns On that way, then you should be able to get the data off the camera.
If it does not turn On, unfortunately, this would turn out to be in vain, and all that I could suggest would be - if the model 696 has a memory card, that you try to get what data you can off of the memory card.
Since that is probably inadequate advice - though I am offering it in good faith and with some hope that it might be of use - I have Opted Out, with apologies, opening the case to other Experts in this category.
